使用外部容器運(yùn)行spring-boot項(xiàng)目：不使用spring-boot內(nèi)置容器讓spring-boot項(xiàng)目運(yùn)行在外部tomcat容器中

前言：本項(xiàng)目基于maven構(gòu)建
spring-boot項(xiàng)目可以快速構(gòu)建web利用，其內(nèi)置的tomcat容器也10分方便我們的測試運(yùn)行；
spring-boot項(xiàng)目需要部署在外部容器中的時候，spring-boot導(dǎo)出的war包沒法再外部容器（tomcat）中運(yùn)行或運(yùn)行報(bào)錯，本章就是詳細(xì)講授如何解決這個問題
1、pom.xml1覽
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

2、排除org.springframework.boot依賴中的tomcat內(nèi)置容器
注意：只有排除內(nèi)置容器，才能讓外部容器運(yùn)行spring-boot項(xiàng)目
org.springframework.boot依賴中的排除項(xiàng)，測試時不要排除內(nèi)置容器，會致使springboot沒法測試運(yùn)行，導(dǎo)出war包時再加上該項(xiàng)便可
<!-- spring-boot web -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
<!-- 排除內(nèi)置容器，排除內(nèi)置容器導(dǎo)出成war包可讓外部容器運(yùn)行spring-boot項(xiàng)目-->
<exclusions>
<exclusion>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
</exclusion>
</exclusions>
</dependency>
3、實(shí)現(xiàn)SpringBootServletInitializer接口
spring-boot入口類必須實(shí)現(xiàn)SpringBootServletInitializer接口的configure方法才能讓外部容器運(yùn)行spring-boot項(xiàng)目
注意：SpringBootServletInitializer接口需要依賴 javax.servlet
package cn.eguid.Run;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;
import org.springframework.context.annotation.ComponentScan;
import cc.eguid.livepush.PushManager;
import cc.eguid.livepush.PushManagerImpl;
import cn.eguid.livePushServer.redisManager.RedisMQHandler;
@SpringBootApplication
// 開啟通用注解掃描
@ComponentScan
public class Application extends SpringBootServletInitializer {
/**
* 實(shí)現(xiàn)SpringBootServletInitializer可讓spring-boot項(xiàng)目在web容器中運(yùn)行
*/
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
builder.sources(this.getClass());
return super.configure(builder);
}
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
總結(jié)：
外部容器運(yùn)行spring-boot項(xiàng)目，只需要在原項(xiàng)目上做兩件事
1、在pom.xml中排除org.springframework.boot的內(nèi)置tomcat容器
2、spring-boot入口實(shí)現(xiàn)SpringBootServletInitializer接口
補(bǔ)充：SpringBootServletInitializer接口依賴javax.servlet包，需要在pom.xml中引入該包
